ARNOLD SOHAER, OF PHENIX, RHODE ISLAND.

STOP-MOTION FOR RAILWAY-HEADS, 84,0.

SPECIFICATION forming part of Letters Patent No. 332,289, dated December 15, 1885.

(No model.)

To all whom it may concern:

Be it known that I, ARNOLD SOHAER, of Phenix, in the county of Kent and State of Rhode Island, have invented certain new and useful Improvements in Stop-Motions for Railway-Heads, &c., of which the following is a full and correct description, reference being had to the accompanying drawings, making a part of this specification.

Thisinvention applies to drawing-machines not using eveners, as well as to those using eveners operated by other means than the trumpet back of the calender-rolls, as described in the Letters Patent granted to me October 30, 1883, No. 287,585.

In the drawings, Figure 1 shows a vertical cross-section of a railway-head with my improvements applied, taken through the lines as, Fig. 3. Fig. 2 shows a front elevation of the same with the drawingrolls, calenderrolls, and their gearing omitted. Fig. 3 is a section plan view illustrating the improvements. Figs. 4, 5, and 6 show enlarged views of a part of the latch-tripping'devices in different positions.

A is the end frame of a railway-head. G G are the drawing-rolls. Bis the trumpet-guide that conducts the sliver of cotton to the calender-rolls. The trumpet B is hung loosely by means of an arm and hub, j, on the shaft V, held in the bearings 70 k,attached to the frame. A collar, 9', is made fast on the shaft V by the side of the hub j of the trumpet-arm. A projection on one side of the collar j comes in contact with a projection on the hub of the trumpet-arm, so as to hold the trumpet up against the friction of the draft of the sliver through the trumpet, which is accomplished by the weighted lever a, which is also made fast on the shaft V. A long arm, a, attached to the lever a extends down through a slot in the lever c, that swings sidewise on a stud, a on the hub of the knee-lever f, which is pivoted to a standard, 62, attached to the frame. The knee-lever f receives a continuous rock-, ing motion from the cam o by means of the lever 0 and the bar m, as described in my Letters Patent above referred to. The cam 0 re ceives its motion through a shaft geared to the driving-shaft. The knee-lever f has a fiat horizontal arm extending out under the short end of the lever c. This arm has a projection the frame, and so placed that its free end shall drop down against the end of the arm 9 on the belt-shipper y when the machine is in motion, and hold the shipper out. (See Figs. 2 and 3.) Two projections, f 3 are made on one side of the lever d, between which projections the end of the lever 0 plays up and down when the knee-lever f is moved by the cam othat is, when the machine is runnin g properly.

The operation is as follows: When the sliver a is running in proper condition, the weight on the lever a will hold the trumpet B up in its proper position, the weight being so adjusted as to just'counterbalance the friction of the draft of the sliver through the trumpet, and in this position the arm a on the lever a will cause theleverc to press lightly on the spiral spring 0 on the top of the knee-lever f, and the stopping devices will be in the position shown in Fig. 4, the end of the lever 0 being free to move up and down between the projections f on the lever d,- but if the sliver breaks or becomes reduced from any cause the friction of the sliver in the trumpet B will cease or be lessened, so that the trumpet will not be held up against the Weight on the lever a, but will fall back and allow the weight on the lever to depress it, and by means of the arm a move the lever 0 so that its end will be under the projection f on the side of the latch-lever d, as shown in Fig. 5, when the upward rocking motion of the knee-lever f will cause the end of the lever c to throw up the latch-lever cl and release the arm 9 of the belt-shipper which was held out by that lever. (See Figs. 2 and 3.) This leaves the shipper free to be thrown toward the frame by the weight a on the arm h, which is fast on the shaft of the belt-shipper, which throws the driving-belt from the tight pulley to the loose pulley and stops the machine. 011 the other hand, if the trumpet B becomes clogged with thick bunches in the sliver, it will be carried toward the calender-rolls with sufficient force to overcome the resistance of the weight on the lever a, and cause the lever c, by means of the arm a, to

compress the spring a and bring the end of shaft V, collar j, and lever a, having the arm the levercunder the projection g on the latcha, in combination With the lever a, lever d, lever d, as shown in Fig. 6, so that the lever having projections f and y, knee-lever f, bar d will be lifted by the rocking motion of the m, cam 0, lever 0, arm 9, lever h, Weight n, and

5 knee-lever f through the lever o, as before, shipper g, substantially as and for the purr 5 and the shipper will be free to cast off the pose set forth.
